【Abstract】 Six glass powders were prepared by conventional melting-quenching method.Conducting phases Bi2Ru2O7,CaRuO3 and BaRuO3 were prepared through solid-phase reaction.The organic matter was also prepared by dissolution.Thus,a series of thick-film pastes were formed by mixture of conducting phases,glass powder and organic matter.The pastes were printed on 96% Al2O3 substrates to form resistors and then dried and fired.The change of resistance values of each resistor after refiring were measured and calculated.The influences of B2O3/SiO2,the ratio of two glass powders and the ratio of two conductive phases on the change of resistance value were studied.Several ways to bring down the change of resistance value were proposed.更多还原
